Abstract: PURPOSE:To manufacture an excellent small diameter sleeve cheaply with a small loss of material by piercing an hole for inserting a wedge having a tapered part at the bottom in a solid rod, drawing to a long size and a small diameter, and forming a slit and a threaded part. CONSTITUTION:A hole 2' for inserting a wedge is pierced from an end of a solid rod. At the same time, a blind center hole 4' of a small diameter is formed from another end leaving a solid part 9 between them as a base body 1' of a sleeve. Then, the solid part 9 is removed by a blow holding the pin of a former on it and a tapered face 3' of reversed conical trapezoid is formed. Then, this base body of the sleeve 1' is drawn to a long body having a small diameter to make the body 1 of the sleeve. A threaded part 7 is formed on outer peripheral face of an end of the sleeve body, and a projection 6 for preventing coming out is formed on the side having tapered face 3. Several slits 5 are cut to divide the projection 6. Thus, a small diameter sleeve excellent in anchoring effect is obtained.

Filed: 1987-04-08
Abstract: PURPOSE:To facilitate the detection and compensation of dropout by dividing two-dimensional data into plural sections, preparing plural bits for dropout information and detecting the presence or absence of dropout in each section. CONSTITUTION:A signal on a magnetic sheet 100 is read (102) and amplified (104), subjected to reproduction process (106) and A/D-conversion 110. A signal from an A/D-converter 110 by one field is stored (114) via switches 120, 122. The memory 114 stores the dropout (DO) information into an area 114B at every scanning line. When DO takes place, the switch 120 is switched to a fixed data generating circuit 112 by the pulse and a specific mark FF is sent to the memory 114. When the scanning of one horizontal line is finished, an address generating circuit 116 sends the address of DO to a reproduction process circuit 106 and a DO information generating section 118, restores the switch 120 and stores it in a memory (114). The specific mark FF of DO is compensated by a data of an adjacent horizontal line. Thus, the detection and compensation of DO are facilitated.
